Humans transmit more viruses to animals than vice versa, study finds [Video]

Many high-profile illnesses, such as COVID-19 and Ebola, originated from animals, leading to the perception that animals are dangerous. However, new research says this may not always be the case. After an analysis of viral genomes, researchers from University College London found a startling trend: humans are more likely to transmit viruses to animals than the other way around. 

The study sheds light on how viral transmission works between humans and other vertebrate species. Zoonotic diseases originate in animals and jump to humans. They are a focus of public health concern. However, the role of humans as the transmitters of viruses to animals is often overlooked.
